WICK-DOUBLER.

Specication of Letters Patent. Patented 211111629, 1920.

Application `filed March 29, 1919.` '.Serial No. 286,013.v

Be it known that I, HARTFORD SWEET, a citizen of the United States, residin at Brookfield, in the' county of Cook and tate of Illinois, have invented a new and useful Wick-Doubler, of which the followingV is a specification.

This invention has reference to wick doublers, and its object is to double a tubular wick upon itself for use in connection with the iodin applicator shown and described in my application No. 301,351, filed June Q, 1919. y f

The Viodin applicator1 comprises a` tube with anV intermediate contracted portion in which there is introduced a doubled tubular wick or swab containing va short glass sleeve of a size to `it in the main tube, with the wick housing it, to the contracted portion of the applicator tube, which latter is sealed at the ends and contains a quantity of iodin or The invention comprises an instrument with a holder at one end,A which holder may be inserted in a tubular wick passed through a short glass sleeve, whereby tohold the wick and sleeveon the end of the instrument; Then a slidable part of the instrument may be pushed along the latter with Ythe portion of the wick surroundedby the glass sleeve-and the sleeveitself held against movement with'the slidable member, which latter engages that-part of the wick, then in single-ply, pushes or doubles such part of the wick about the glass sleeve and upon itself. The

' sleeve and the doubled or two-ply wick may then be removed from the instrument and the wick cut off to a suitable length, or while still on the'instrument may be cut oi to the desired length and the'instrument used to introduce the double wick into. a container for the, iodin or other material employed.' The extent of introduction-is determined by a .contracted portion of the container, whichv may be of glass and'sealed at one end, before the double wick or swab is introduced.' The instrument is then removed leaving the wick in place with the glasstube embedded in the wick 'serving as a-stop, and then the other endof the container is sealed-,thus preserving the contents `of the container from .loss

\ emergency kit.

around the instrument and cator is particularly valuable for the dressing of wounds and mayV forml'part of an The invention has to do particularly-with the'rapid formation ofthe doubled wick or swab and. means for readily introducing it y into the'container. 4

-The invention will "bebest understood from a consideration of the? following detailed description taken in lconnection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined toany strict conformity with the showing of the drawing, but may be changed and able member for effecting the doublingy of',`

the wick partially advanced in such opera-V tion.

Fig. `fl: is a section similar to that of Fig.

3 but confined to the left hand portion thereof and showing holding prongs projected. y. A' y v l Fig. is an elevation ofthe member provided with the prongs.

-FignV is a View, partly-in longitudinal section and partly in elevation, of a modiiied Y form of the tubular instrument.

Fig. 7 is a longitudinal section of the doubled wick or swab 'inclosing the glasssleeve. f

Fig-8 is a longitudinall section of still Y another form of the invention. l

Invthe drawing, there is shown a tube 1, of appropriate length constituting abody member, and inserted in one Vend of the tube 1 there is a tubular nose v2 having a-icon' tinuation 3 Awith diametrically opposite lon` gitudinal slots 4 therein, l the extremityof the nose being closed as indicated at' 5;

i Within the tube 1 is another 'tube 6 concentricvwith the-turbe 1 and extending away froml the nose 2 to a like extent, the two;

tubes'beingsecur'ed' together at their .rear

7 to which both tubes may be soldered or otherwise fixed. It will be understood that other means may be employed for holding the two tubes in fixed relation to each other. y

tinuation 3 of the nose 2.

Surrounding the body t'ube 1 atthe rear end thereof andliiXed to said body member by a spacing ring 11 is'another tube 12 constitutinga handhold. The tube 12 is considerably shorter than the body tube 1 and mounted on said*y body tube is alongitudinally movable sleeve 13 having arange of Y. travel from abutting-relation with "the handhold 12 to a position beyond the nosen end 2.

InFig. 3 the tubes 1, 6,12 Aand 13 are shown as fconcentrically arranged vtubes considerably spaced from-eachother in their concentric relation, but it will be Vunderstood that these tubes `may have only such spacing where they have relative movement on each otherv to permit such movement without binding. f

vThe rear endoithe tube V13 is entered by a tubular push piece 14 having a head or thumb piece k15 at thevend remote from that entering the tube 13. The push'piece 14 is so arranged that Vit is ,capableoii limited longitudinal movement inrtelescoping relation to the tube 13, and fast to the head or thumb piece 15 isa rod 16 extending lengthwisev of the push piece and movable therewith and through a guiding collar 17 fast in theA rear end of the tube 6 and then carg ried forwardly to about the rear end of the .y nose piece 2. Between the collar 17 and theV thumb lpiece 15 there is confined a spring 18 surrounding the rod`16, the tend-V ency of the spring being to retract the rod' 16 but is yieldablevv-to -a force applied'fto the thumb piece -15 topush theV forward end of the rod 16 between vthe approached ends, ofthefingers 9. NVhere *they ,prong ends of the fingers 9 come in'contact, such fingers are bent to provide Vbevel shoulders 19 in the path ofthe forward end of the rod 16-sothat'when thepush piece 14 is forced into the tube 13y against the tendency of the springf18 the forwardend of .the'rod A16 engages thebevel shoulders 19 and thereby spreads the 'orward-'endsof the fingers 9.

and causes the projectionof the prongs 10, this being shown in Fig. 4.V When; pressure upon thehead 15Vis released "thespring 18 returns the Aparts to their normal position shown -in Fig. 3, thereby retracting the prongs 10 so that they no longer project beyond the surface of the extension 3 of' the nose 2.

lhen the instrument is to be used a short sleevev20, whichfmay be and preferably is made of glass tubing, has a piecejof hollow wicking 21 threaded through it, such wicking being of tubular weave and'may'fbe cotton wicking-The wickingV projects beyond one -end of the sleeve 2O to an extent.

permitting the projectingend Lto be'pushed uponthe forward' end yof the body tube 1 to a desirable extent `and theV sleeve 2O is applied to the extensiony 13 oi thenose2,

whereupon, the vpush piece 14 isV advanced causing theprongs; 10 `to Yproject andvk engage that portion of the wi'cl'ringiorward of the s'leeve20. Now,the movable sleeve orv tube v13 is rpushed forwardlyengaging that end of vthe hollow wick 21 upon the forward endvo the body vtube 1, thereby pushing the wick iin rfront of it .toward the sleeve 20, thus forcing the wick over the sleeve. Because thersleeve20 is heldfonto thefnose extension'3 by the projected prongs i is lodged on one: side of the contracted-por-n tion of the container and the free ends oi i the doubled vwicking project 'through the contracted-portion to the other Vside of the latter.

1 Thel instrument may be utilized for plac-l ing the doubled wicking into thecontaincr and this may be done without removing the doubled wickingjafter thedoubling has been accomplished,I since the-free .ends of the doubled wicking may be cut olfto the desired length ,while the prongs v10V are still in the projected position. lVhenwthedou- Y bled wicking or swab lis vplaced ,in the` cen-j tainerl to the desired position the instrui ment may be released from the wicking by' retracing theprongs 10 and-the device may be easily withdrawn from the container,

leaving the wicking therein. -In Fig. 7 the completed swab is Ashown i-nclosing the sleeve -20 and the wickingV 2`1'indicagted in the-doubled-eondition. j In Fig. 6 a simpliiedform of their-istrumentis indicated, s howinga rod 22, which may be of tubular form if desired, and atf one end this Arod'hasjan-'enlarged or` handle vportion 23 while at the -other end-there isf anose-projection 3@ provided with exteriorscrewfthreads 24. Mounted on the rod'22 so as to have relative .longitudinal movement with respect Vthereto is a sleeve 25.y The rod 22 carries an j exterior collar 26 fixed thereto and the sleeve 25 has at one end an interior collar 27 fixed thereto. The

sleeveor tube 25 has a range 'ofmoveinent between the handle 23, whichis larger than the rod 22, and the collar 26, this range of movement being suficient-to carry the forward end oftheftube 25 over and beyond the nose' end 23.k When it.` is desired to Y double the wick around the glass sleeve 20, e the wick is threaded throughthe sleeve as in the structure fof Fig.` l, `and theproj ecting portion of the sleeve is threaded overthe forward end of therod 22." Then therod 22 is turned about its longitudinal axis so that' the screw-threads 24 move into the sleeve 20 in engaging relation tothe portion wicking isl engaged thereby and returned over the sleeve `20 and beyond thelatter,

thus doubling the wick in the same manner as in Fig. `1 and associated figures. j Then' by cutting offthc surplus wick the. doubled .j y l p vscribed,comprising an elongated body porwick maybe introduced into the container to the desired point and the doubling in-` strument may be withdrawn by unscrewing the end 3@ ofthe rod 22 from engagement with the wicking insideof the sleeve 20.

In Fig.' 8, which illustrates still another Jforni of theY invention, there is shown a tubular body member 28 contracted at the forward endfinto a tubular neck 29 open at both ends, ywhile the rear end ,et the body member isclosed by a cap 30. Within the body member are fingers 31 joined at the rear-ends by a yoke 82 between which and the cap 30 the body member houses a spring 33, connected to the cap and to the yoke, thereby constantly tending to .retract the fingers 31.

The forward endsv of the fingers project through the neck 29 and arethere provided with spear heads 34 so that these heads will tend to confine a vsleeve 20 between them and the end of the body 28, which latter, where joining the neck 29, forms a shoulder or abutment 85. V

ySurrounding the body 28 is a longitudivnally slidable tube 36 having longitudinal slots 37 to passheaded pins 38l on the relap lied to the instrument.V l -r 34C will overlap similarly to the action of theblades of shearsand then a sleeve 2O with apiece of tubular wicking 21 threaded therethrough may beslipped upon the neck .29' with the extended portion of `the wick over the `adjacent portion ofthe body 28; On releasing pressure upon the pins`38 the spear heads 34: will separate and confine the "sleeve 20 between them and the shoulder 35.

By providing some" play where the pins 38 extend through the body member 28 theV heads 34C willfengage and holdthe sleeve 2O with sufficient force against vthe slioulder 35.-' 1 5 New, on moving the tube lengthwise of the body member 28, the wicking v21 is engaged as inthe other structures andreturned uponitself so `as tofhouse the sleeve 20. Then by pressure applied to the pins 38 the heads 34a-re moved out of the way of the sleeve and the doubled wick housing the sleeve 2O is readily removed from the instrument, or the wickingmay be cut voii' to the desired length and introduced into the container of the applicatorv in the vmanner liereinbefore described.. The spear headsBd maybe-so shaped as to avoid catchingv in the wicking when the latter 7Vhat is claimed is Y l."
